  another way to do it for all kernels is to add the
options to apt itself (in /etc/apt/apt.conf or ...)

  i set options to make sure apt doesn't get rid of
my saved cache files without me explicitly requesting
it and there is another option for setting which files
are never marked for autoremoval.

APT::Clean-Installed "false";
APT::NeverAutoRemove  { "linux-image.*";  };  // packages that should never
                                            // considered for autoRemove

  i no longer see grub menus very often (using
uefi boot menu and refind).
